Can Ducks Eat Kale? (Everything To Know)

Can Ducks Eat Kale?

Kale is an excellent vegetable that fits almost every dish. The green vegetable provides a huge variety of nutrients and is seen as many as the number one vegetable due to its dense nutrient content. Not only do humans enjoy the leafy green, but also our two and four-legged friends. Farmers often have problems with animals visiting and trying to eat their kale. Perhaps they also know the benefits of eating kale. How about our bewinged friends?

Ducks can eat kale, and they certainly love it. Kale is great for adding into their regular diet, serve on its own, or even do things with, like mashed potatoes or smoothies. Kale adds Calcium and Potassium, which are paramount in a duck’s diet. However, feed in moderation due to its water content.

Raw kale is about 84% water, which can be a problem for ducks if not fed in moderation. Eating food with high water content may cause diarrhea and make them feel bloated. You can deflect this with foods like oats that inhibit diarrhea.

You can feed kale to ducks in different ways. For example:

  • Raw
  • In smoothies
  • As chips
  • In mashed potatoes
  • Salad
  • Soup

Safe ways of feeding kale to ducks

Safe ways of feeding kale to ducks

There are numerous ways to feed kale to ducks in a safe way. I will share my 8 best tips to serve the fantastic vegetable to your ducks in a safe way. I hope you will try at least one f them.

1. Cut, massage and put them to a bucket of water

This is the simplest of all ways to feed kale to your ducks. The only thing you need to do is to cut the kale up into tiny pieces. You can cut multiple leaves at the same time. Fold the kale when cutting to both save time and making it sturdier to cut. After the kale has been cut, add it to a bowl, and massage it. You will soon notice how the stiffness is disappearing, and it almost feels like handling iceberg lettuce. When you are done massaging the kale, add it to a bucket of water. Simple as that!

2. Cut, massage, and mix with their other foods

This method is just as simple as the first. Cut the kale into small pieces by using the folding method. Massage the kale in a bowl—mix in some of the pellets you usually feed your ducks with, ready to serve.

3. Make a kale smoothie bowl

Feeding your ducks a refreshing smoothie is a great way to ensure they receive all the nutrients for the day. You can add fruits, vegetables but also Kale powder to boost the antioxidants even more.

My duck’s favorite smoothie bowl recipe includes:

4. Kale soup is awesome

Kale soup is another super-easy way to give your ducks’ kale safely. The soup doesn’t even need to be heated and can be served cold. It’s easier if you cook it, but you will need to serve it cold.

I cut the kale using the folding method. I cut carrots into smaller pieces and cut potatoes in half. Boil everything for 20 minutes. When it’s done, I add some KalePowder. After that, I use a stick mixer and blend it until it has a good texture. The starch from the carrots and potatoes thickens the soup.

You can do this by yourself, but I suggest adding some leeks, onions, garlic, and maybe a bouillon cube. These shouldn’t be offered to ducks since they are toxic.

5. A simple salad

You can make a simple salad your ducks will enjoy. The ducks will become a bit boring if served to humans. You can’t add any spices or oil, making it pretty dull.

You can add the following to the kale salad for ducks:

You will need to grate the carrots, chop the tomatoes, slice the apples, cook, and cut the broccoli.

Never add avocado, baby spinach, green onions, lemon, or oranges to the salad.

6. Make mashed potatoes with kale inside

Making mashed potatoes for ducks is really simple, and they really like it. You can hide other vegetables inside the mashed potatoes to boost the nutrient content even more.

How to make mashed potatoes for ducks

  1. Peel the potatoes and rinse them.
  2. Boil the potatoes in unsalted water for 20 minutes.
  3. When the potatoes are done you move them from the pot into a bowl
  4. Save the cooking water.
  5. Mash the potatoes with a potato masher.
  6. Add some of the cooking water to help it get it into a mashed potato texture.
  7. It’s ok if there are some small pieces of potato left.
  8. When you are feeling satisfied you are done.

You can add chopped kale, broccoli, peas, or grated carrots. The options are endless.

7. Make kale chips

Making kale chips is an effortless way to feed kale to your ducks. It’s the same method to use when doing potato chips for ducks or apple chips for ducks.

How to make kale chips for ducks:

  1. Preheat the oven to 150° C or 302° F.

If you make them for yourself, you add oils, salt, and spices during step 5.

Last but not least. The ducks deserve some dessert. Giving your ducks nice cream using frozen bananas is an excellent way to make them eat many vegetables and get their vitamins. You can add Kale Powder in the nice cream mix along with both kale, bananas, peas, broccoli – you name it.

Unsafe ways to feed kale to ducks

There are three major risks when feeding kale to ducks. I will give you my best advice to be aware of when feeding ducks kale.

1. The bits are too big

It’s easy to miss, and sometimes a kale leaf can be treacherous. Feeding ducks too big pieces may cause them to suffocate. The best way to chop kale is to use the folding method. When you fold the kale multiple times, the pieces become smaller when cutting. After chopping the folded piece, rotate it 90° and cut it again, making the pieces even smaller.

2. Leaves are moldy

Make sure to check the kale after mold before serving it. Mold in kale looks like black dirt on the leaves. If you see mold on kale and it has been in contact with other kale, it would be best to throw out all leaves in contact with it. Mold spread quickly and is very harmful to ducks.

3. Not feeding in moderation

Although kale is very nutritious and healthy, it can be a problem when feeding too much of it. Kale is 84% water, and eating too much kale may cause the ducks to have diarrhea. Diarrhea can cause dehydration and may hurt their kidneys.

How much kale can I feed my ducks?

How much kale can I feed my ducks?

The amount of kale you can give your ducks is determined by how much other food you are giving them. Ducks need a specific caloric intake (check with a veterinarian if you are unsure how much your ducks need). If you increase the amount of kale in their diet, you will need to decrease something else. You will also need to be aware of increasing the other foods when increasing the amount of kale in their diet. Kale has high water content and may cause diarrhea. Therefore, it’s also good to adjust the number of foods that inhibit diarrhea. Foods like oats, bananasapplesaucerice, and potatoes are great additions to a kale-rich diet. If you aren’t fond of the idea of adding more food to their diet but still want to give your ducks the benefits kale brings, you might want to grab a bag of Kale Powder. It has the same nutritional value as kale but lacks the amount of water. Win-win.

How often can I feed my ducks’ kale?

How often can I feed my ducks' kale?

Feeding your ducks kale daily might be a good idea if you have control over their other foods. A diet rich in kale may lead to diarrhea unless you also provide them with inhibiting foods. While kale is low in calories, it can be served in high volume and still provides many nutrients. However, it still takes up room in their stomach without providing much energy. A good balance between other foods and kale is key to have healthy ducks. You can add kale powder to their diet and let them fill their bellies with foods that provide them more energy. A bag of kale powder lasts 45 days for my ducks and is pretty inexpensive comparing to other foods.

How do I store kale the best way?

How do I store kale the best way?

I prefer to store my kale in the freezer using the method described in the video below. I remove the leaves from the stem, chop both separately, and store them inside a good plastic bag. Pressing the bag and trying to flatten it removes the air inside, making it easy to seal. I meal-prep on Sundays and prepare bags for every day the upcoming week.
